MACHINE FOR EMBOSuSIN G- HATS.

The Schedule referred tojn these Letters Patent andmakng part of the same To all whom it may concern: y

VBe it known that I, RUDOLF Freuen/Invert, of Yonkers, in the county of Westchester, and State of New York, have invented certain Vnew and useful Imtated eitherby 'an eccentric or concentric lathe, an

embossing-tool, held, guided, and moved in the required path by the machine, so as to impress spirally a pattern or figure of waving or plain lines upon the crown and brim ofra hat, in a regular manner, subystantially as hereinafter described.

I will first describe that part of the machinery 'd'esigned for embossing or impressing a spiral ligure upon the tip and side crown ot' the hat, illustrated by figs. 1, 2, 3, and 4, oi" the drawings. l

Figure 1 is a vertical section of said part of the machine.

Figure 2, a' detached plan view of pattern-guideand `spring-pressing foot for guiding the embossing-roller.

Figure 3, a detached plan view of part of the mechanism for giving motion to the swinging frame vwhich carries the embossing-tool.

Figure 4, a detached plan view of gearing, shown in ig.'1.

Alis a4 frame or table, which supports the lathe-head B of a common oval lathe, to which the hat-block C is secured in the usual manner. i

D is the cone-pulley, for driving the lathe-spindle.

The embossing-tool I prefer to use is a roller or wheel A, of suitable' width for the lines to be embossed. The face of the roller may he smooth or have a small ligure cut upon it, or may be scalloped or made in any way desired, so as t'oimpress'a figure in lines upon a hat placed upon the hat-block, by rolling ,on the hat, in consequence of the motion of the hatblock. Rubbing-tools' may, however, be used like those shown in Figure 'l'. Y

' The embossing-tool or roller is mounted in suitable bearings upon a short spindle, m', which plays in a sleeve, m", adjusted bya screw, m ,and supported and carried by a small upright swinging frame, G, which swings on pivots l' within a larger upright swinging `frame, F, which latter is pivoted at K upon the verticalspindle E, so that it is movedaround the hat-block by the oscillation of the spindle E, and moves toward and from the bat-block, upon the pivot K being drawn -toward the hat-block by the pressure of a weight, K',

which acts upon the swinging frame F through the 'hellcrank I, and links q being connectedto the bell-crank 'by a. cord, X, running over pulleys y y1 yz, as shownv in the drawings, the arrangement being such as to give less pressnreyof the embossing-rollerpat parts of the hat where the motion is the slowest.

A stationary guide-plate or pattern, O, shown detachcd in fig. 2, made with a curvature corresponding tothe curve of the hat-crown, guides the embossing- -roller hymeans of the spring-pressing foot p, which having a flat surface acting upon the guide-plateO,

holds the swinging frame G in position to present the face of the embossing-tool Vproperly to the different parts of the crown of the hat!A i The embossing-roller is partly enclosed in a rollerhouse, m, heated vby a gas-llame, n. The lower part of' the roller-house may contain color, if it is desired the embossing-roller.

The weight of the swinging frame F is balanced by a weight, H, attached to the bell-crank I.,

In order to produce a regular spiral gure upon the to use color, in which case a scraper mustbe used upon hat by the embossing-roller, it is necessary'to Vary the speed of the motion of the swinging frame, as it oscillates from the centre of `the tip to the base of the side crown of Ithe hat, because the hats vary in outline from the arc of a circle. This is accomplished as follows:

Upon the lower part of the spindle E, which carries the swinging frame F, is placed a hub, L, to which.is attached a pattern-cam or block, s,` ot' the required shape to give the irregular speed necessary for the particular hat-shape operated upon 5 the motion being imparted by a strap, j, attached at one end to the hub L, and which, passing around the pattern-cam or block s, is attached at the other end to a barrel, i, loose upon a vertical shaft, j, and connected therewith by a coupling-clutch, g h, controlled bya clutch-shipper, W.

Alever, Z, which is pivoted upon the shaft f, ex-

tends horizontally forward to the pattern-cam s, and carries a guide-pulley, r, to keep the strap j to the face of the pattern-cam.

Motion is `communicated to the shaft f from the lathespindle, by bevel-wheels a a', shaft b, pinion c, spurwheel d,'pinion c', and spur-wheel d. Y

- A weight, N, is connected with the barrel i, upon the shaft f, by means of a cord, fr, as shown in the drawings,;for the purpose of moving back the swinging frame when the clutch-coupling is released.

In operating this machinery, the hat being placed upon the block, the operator seizes the handle F1 of the swinging frame F, and adjusts the embossing-roller to the centre of the tip of the hat. rJlhe machinery being then set in action, the hat revolves, and the embossing-roller is guided by the machinery so as to impress upon the hat a regular spiral figure, of waved or plain lines, beginning at the centre of the tip, and terminating at the base of the lcrown the patternplate and does notI require so much skill and attention on the part of the operator.

I will now proceed to describe the machinery for embossing or impressing the brim with a spiral figure,

' by means of a rotating block or brim-board, and an embossing-'roller or other embossing-tool. This part of the machinery is represented in gs. 5 and 6 Figure 5 being a side elevation of the machine, partly in section, and

Figure 6, a rear elevation of the. same.` also partly in section.

Letter A represents a frame or table, which supports an oval turning-lathe, D, carrying the rotatory hat-block C and brim-board C.

In this machine the embossing-roller is held against the brim-board by a swinging frame, X', pivot-ed to a rocking-shaft, E, a weight, Q, being attached by a cord to an arm of the swinging frame.

This swinging frame X' may be moved by hand -to impress a spiral pattern upon the brim ofthe hat, but I prefer to move it by mechanism connected with the lathe-head, as follows:

A worm, o, upon the rear end of the lathe-spindle, gives mot-ion to the worin-wheel P, which, in turn, gives motion to the barrel V, and through a cord to the lever T in the rock-shaft E, a weight, R, acting on the arm when the wheel is not in gear with the worm.

A shifter, Y, throws the worm-wheel in and out of gear with the worm.

and the embossing-roller allowed to operate, gradually mo'ving over the surface ofthe brim in spiral lines, im-

pressing a spiral figure.

In case it is 4desired to impress a scalloped spiral figure upon the hat, the lathe-head may be set upon longitudinal pivot-bearings, and provided with ascalloped pattern-plate, s, attached to the cone D, and a pattern-roller, W, supported by a stationary bracket, U.

The lathe-head being pressed over by a spring, so as to keep the pattern-roller in contact 4with the pattern-plate, theresult of the operation of the machine will be a scalloped spiral figure embossed upon the brim of the hat.

The machinery rst described may be used for both crown and brim, by simply turning the swinging frame G at right angles when it gets to the brim, and gradually depressing the larger swinging frame F by means t of the handle F1, so that the embossing-roller will travel over the brim,y but I prefer to use different machines for the two operations.

I claim- 1. In combination with a rotating hat-block, an embossing-tool or roller, held in a swinging frame or its equivalent, substantially as described, so as to be capable of impressing a figure in spiral -lines upon a hat revolving with the hat-block, substantially as described.

2.' In combination with the revolving hat-block, embossing-tool, and swing-frame, the guide O, and camgnide s, whereby the position of the embossing-totlis regulated, and the regularity of the spiral vfigure uptn the tip and crown oi' the hat insured, substantially as described. i

3. In combination with the revolving brim-bead and embossing-tool, the swing-frame and mechanism where` by it receivesv motion for guiding the embossing-tool, to impress a spiral figure upon the brim of a hat, substantially as describei l R. EICKEMEYER Witnesses: Y 1
